[Resolved] Uploading Multisite plugins to the sub directory

I was thinking of this or how I can achieve this. So, I have published two multisites website and there running good..My concern was the plugin and themes, I mean I have the blog.dir and mu-plugin folder but when I do upload a new plugin or theme it wont go there. Is there a way to do it?? I mean, if I used a theme for my main site and used it also on my subsite but with different styles, How can I get that to work..?? One sample of my multisite is this one http://www.drheatherlariviere.com/…If I want to change the background color or image for the french page?? How can I get to achieve it,..??

Well yeah…Thats what its doing..So, those mu-plugins and blog.dir folders I created are nothing to do..So,how about if I used similar themes but different styles on them? How can I get to achieve it?? Or should I just rename the theme so that its a different but similar??

Is this a new multisite that you are building? I ask because you say that you created a blogs.dir. You may not need that directory. If it’s a new install created with WordPress 3.5 or later, it won’t use that folder any longer. If it’s an older one, it’s fine if you have it.

For your question, however, if you are interested in having different color schemas on subsites using the same theme, you should consider using a child theme. To understand more, please consult:

http://codex.wordpress.org/Child_Themes

Essentially, your child theme will pull in information from the Parent theme and then load the child theme information unique to a subsite. And further, if you have a unique name for your child themes, you can have as many children to a parent as you like.

If you bought your theme, many theme authors will have child themes premade for you and you might easily just grab one, install on your network and activate on the sub-site that you want it on.

There IS a reason for this: If someone can edit your PHP files, then they can use that to write code that gives them access to the REST of your install and, logically, your server. It’s a HUGE security hole, and WP would rather protect you.

If everyone needs to be able to customize their themes and plugins, you’re better off with multiple single, separate, sites.

If the themes need to be customized then you need to either do it yourself with FTP / SFTP or put the users on their own hosting accounts so they can do it on their end.

Hahaha… Well, thats my concern…Different styles on different websites with the same theme..Just like this sample http://drheatherlariviere.com/…You can see that the french and english is on same layout..So, I was wondering If I change the layout of the french without using another theme.Just the same theme as the english site.
